How much faster is the speed of light than the speed of electricity without using superconducting materials eg in normal computers?

We generally consider that the force of an electric field moves at the speed of light. And electricity moves at the speed of light.

Does computer work without electricity?
no you cannot turn it on without electricity or some type of battery but, no it wont work
What are some inventions we couldn't live without?
It's Electricity !! affortable electricity by Nikola Tesla. Tesla perfected the AC generator design, making electricity practical and cheap. Without Tesla, we will still have electricity, but it will be very expensive.
Can an electrical starter turn without electricity?
No, an electrical starter can not turn without an electrical source.
Importance of computers in advertising?
Of course computers are important in advertising! you wouldn't be able to make advertisments if you didn't have computers. A lot of ads have computer generated effects or animation, this wouldn't be able to be done without computers.
What is the logic behind flow of electricity without circuit?
current
What are crystalline structures that conduct electricity without resistance when cooled to a certain temperature?
Superconducting materials.
How would a superconducting material at room temperature be useful?
Most superconducting materials have to be very cold. Getting materials this cold tends to require the use of a lot of energy. The idea behind superconducting materials is to transfer energy more efficiently, without energy loss due to such things as heat. So, expending energy to save energy defeats the point. With a superconductive material at room temperatures, we could do things like send electricity for long distances without losing any of the electricity along the way. Electricity could be generated in wind farms on the plains and sent to houses on the coasts with no loss. It could make computers more efficient as well by allowing the creation of super-fast electronic switches. This is done by sandwiching a thin insulating layer between two pieces of superconductive material.
Materials which lets electricity go through them are called?
Conductor are materials that conduct electricity. There are also semiconductors, which conduct electricity but not as well, and superconductors, which conduct electricity without resistance when very cold.
What can't we use without electricity?
Anything from computers to cell phones to lights to refrigerators. The list is nearly endless.
How you can safely remove the item from the water without harm to yourself or others?
well you can have insulated materials that do not bond with electricity.
What would you do without electicity?
if we did not have electricity it would be very cold,dark and there would be no tvs, no radios or there wouldn't be any computers either.
How does science play a role in your everyday?
TV, Radio, Computers, Cars, Telephone, Electricity, none of these would be possible without science.
Why is it power electricity is important in our todays society?
Electricity is important to our society today because without electricity you can not live.The reason why electricity is the following.House hold.-fans-light bulbs-televisions-ovens-heaters-refrigeratorsEducations-lights ( to see)-computers-interactive white board.
Can electricity be generated without using man-made materials?
yes electricity collects in clouds to form lightning and in living organisims such as the electric eel. Also static electricity can be generated using friction (in hair for example).
What runs on electricity?
Some cars, mircowaves, computers, toasters, hair dryers, cell phones. People wonder how cell phones run on electricity it's because the battery inside the cell phone is powered by electricity. Without electricity the battery would die out after a while.
What can electricity do?
Here in the 21st century we use electricity to power many items such as: ipods, computers, kitchen appliances lighting. Electricity can also kill you by causing all your muscles to contract and eventually killing you. So in conclusion in the 21st century it would be difficult to live without electricity.
Would it be harder to learn in a school without electricity?
It wold be really hard because there would be no lights, no TVs no no computers. It would be so hard.
